Hi A.J.
I agree with just about everything you mentioned! There are some solo instrument sounds I like better on the 2000. The Cool E guitar, Growl Sax, Vintage Amp and Vintage Open Guitar, to name some
The PA80 has the best-sounding harmonica I've ever heard, and the realism of the drums is outstanding. I also liked the way you could write different style variations for chord variations (minor, major 7th, etc.)
I could have waited for the fill-in upgrade, but I couldn't live with the Korg's limited Vocal Harmonizer.
The individuality of the Styles is a Love/Hate sort of thing. The Korg styles are very realistic and expressive, but the more "generic" quality of the Yamaha styles better suits my style of playing. I found that because the Korg styles ARE so busy and full, that the player becomes less important. (The same can be said for Solton). The Yamaha styles provide a good, solid, backing "bed", but leave room for me to add individualism to the song I'm playing.
It's funny how certain areas are very important to one person, and then may not make any difference at all to the next person. It all depends on how you use the keyboard.
